Subd. 1a.Fees.

All plans and specifications for public pool and spa construction, installation, or alteration or requests for a variance that are submitted to the commissioner according to Minnesota Rules, part 4717.3975, shall be accompanied by the appropriate fees. All public pool construction plans submitted for review after January 1, 2009, must be certified by a professional engineer registered in the state of Minnesota. If the commissioner determines, upon review of the plans, that inadequate fees were paid, the necessary additional fees shall be paid before plan approval.

Plans submitted less than 30 days prior to construction are subject to an additional late fee equal to 50 percent of the original plan review fee. The commissioner shall charge the following fees for plan review and inspection of public pools and spas and for requests for variance from the public pool and spa rules:

(1) each pool, $1,600;

(2) each spa pool, $900;

(3) each slide, $650;

(4) projects valued at $250,000 or more, the greater of the sum of the fees in clauses (1), (2), and (3) or 0.5 percent of the documented estimated project cost to a maximum fee of $15,000;

(5) alterations to an existing pool without changing the size or configuration of the pool, $700;

(6) removal or replacement of pool disinfection equipment only, $200; and

(7) request for variance from the public pool and spa rules, $550. §
